Metabolism Practice Exam Bis2A / Gerhart. I NSTRUCTIONS Y OU LL BENEFIT MOST IF YOU TAKE THIS PRACICE EXAM ON YOUR OWN , WITH NO NOTES AND WITHOUT LOOKING AT THE KEY . It will also help you if you WRITE DOWN your reasoning for each answer. Why are the answers you didn’t choose “wrong”? After you’ve taken the exam, score each question in terms of the level of understanding (from Bloom’s Taxonomy) required to answer it. The questions in this practice exam represent the types of questions that you might see on the actual exam (and they are in fact old exam questions from Bis2A). They are typical of the level of thinking that will be required of you. The exact topics and examples will, of course, be different …so. .. PLEASE DO NOT assume that studying this practice test will be sufficient preparation for the exam. The actual exam will be about half this long – it will have approximately 30 multiple choice questions, and about 1 page of multi-format questions.
